Miami-Dade Transit’s Metrorail and Metromover service and traffic is being temporarily affected as President Barack Obama landed at 5 p.m. Wednesday at Miami International Airport.

Afternoon rush hour traffic from the airport to Miami Beach will be stopped or rerouted as the president’s motorcade crosses town.

For security reasons, several Metrorail and Metromover stations will need to stop service momentarily. Metrobus service, in and near downtown Miami, also will be affected.

Miami-Dade Transit is asking passengers to be patient and plan accordingly since Metrorail and Metromover will cease operations intermittently, with service interruptions for as long as 25 to 30 minutes.

Metrorail riders who plan to use the Orange Line to go to Miami International Airport are encouraged to build in extra time for the trip.
